Study Notes
What is a Computer?
- A computer is an electronic device that takes in input, processes information, stores data, and produces output.
- It can perform a variety of tasks, such as calculations, data storage, and communication.
Basic Components of a Computer
-
Hardware: physical parts of the computer, including:
- CPU (Central Processing Unit): executes instructions and performs calculations
- Memory (RAM): temporary storage for data and programs
- Storage (Hard Drive or SSD): long-term storage for data and programs
- Input Devices: keyboard, mouse, scanner, etc.
- Output Devices: monitor, printer, speaker, etc.
-
Software: programs and operating systems that run on the computer, including:
- Operating System (OS): manages hardware and provides interface for user interaction
- Application Software: programs that perform specific tasks, such as word processing or web browsing
Types of Computers
- Desktop Computers: designed for use at a single location, often more powerful and customizable
- Laptop Computers: portable and designed for mobility
- Tablets: touch-screen devices with internet connectivity and limited keyboard functionality
- Smartphones: mobile phones with computing capabilities and internet connectivity
- Servers: powerful computers that manage and provide access to network resources
Computer Generations
- First Generation (1940s-1950s): vacuum tubes, limited functionality
- Second Generation (1950s-1960s): transistors, smaller and faster
- Third Generation (1960s-1980s): integrated circuits, more powerful and efficient
- Fourth Generation (1980s-1990s): personal computers, graphical user interfaces
- Fifth Generation (1990s-present): internet-enabled, mobile devices, artificial intelligence
